Hot Particle Drag in Compressible Gas [PDF]
Aerosol Science and Technology, 1990 This paper examines the drag force felt by relatively large (250 micron) MgF2 particles moving inside the exhaust of a magnesium-teflon flare burned at reduced pressure (0.02 atm). It is shown that the well-known Stokes formula for the drag on a spherical particle must be modified to take into account the MgF2 particles' elevated temperature with ...

Atomic structure of hot compressed borosilicate glasses [PDF]
Journal of the American Ceramic Society, 2020 Abstract Borosilicate glasses have been in widespread use for over a century; however, a detailed understanding of the structural response to densification is still lacking. In this work, two commercial borosilicate glasses, viz., SCHOTT N‐BK7 ® (N‐BK7) and Borofloat33
